The greater amount of eumelanin in darker skin protects folate from being broken down by UV radiation and thus increases fitness among populations in high-intensity UV areas. ... However, it does not explain why there is variation in human skin color.
The process by which oxygenreleased into the atmosphere by photosynthetic organisms is taken up by aerobic organisms while the carbon dioxide released as a by-product of repiration is taken up for photosynthesis. Origin ofoxygen cycle Expand.
Answer:
The potential risks associated with plant-based pharmaceuticals include: pollen transfer to related species, contamination of non-transgenic crops intended for the consumption by humans, allergic reactions to the drugs produced from the genetically engineered plant, and persistence of genetically engineered material to persist in the environment and accumulate in non-target organisms. Risk assessment of plant-made pharmaceuticals should be reviewed on a case-by-case basis because the plants used to produce proteins each have different risks associated with them.
Its true i took a test and got this one right
Answer:
The organism to have maximum energy would be the algae since ii will be at the lowest level. so the answer is 'B'.
Explanation:
The pyramid of energy shows the flow of energy from one trophic level to other. The lowest trophic level is occupied by the producers. In this case algae acts as the producer. Krill acts as the primary consumer, followed by leopard seal as the secondary consumer and finally killer whale as the tertiary consumer. The <em>lowest trophic level </em> contains maximum energy.
As we go upwards, only 10% of the energy gets transferred to the next trophic level.
